On Monday, for example, Palestinians activists began circulating an image allegedly showing a father carrying his daughter to her grave this week in Gaza. You can see the very graphic image here.

Israelis online soon pointed to a link for a Reuters photo correction as evidence that the photo was actually from 2006. According to the correction, the girl had died in a swing accident, not an attack.

One Palestinian activist apologized for sharing the old photo:

Warning/Apology: Photo I tweeted earlier which has been circulated over FB turns out to be old photo of Raja Abu Sha’ban killed in Gaza 2006

A second photo was shared by Palestinians online Saturday, beginning with Palestinian activist Maissam Nablussi on his Facebook page. Nablussi called the photo “one of the strongest explosions” in Gaza Saturday:

But after Israeli activists pointed out the photo showed an Israeli airstrike on Gaza as part of Operation Cast Lead in January 2009, Nablussi quickly removed the photo from her Facebook wall.
